Curved Drill Deflector Attachment for Hard-to-Reach Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling devices and drilling resistance measuring devices are limited in their ability to perform drilling or resistance measurements at locations that are difficult to reach, such as the ground level or above head, requiring complex evaluation software and challenging positioning.
Innovation Solution
A deflector attachment that allows the drilling needle to be guided at an offset angle from the drill axis, enabling the drilling device or resistance measuring device to be retrofitted with a curved deflector housing for easy access to hard-to-reach locations, using either rigid or bendable deflector housings with adjustable angles and fastening means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional drilling device is used with a straight drill axis, then the device structure is simple and easy to operate, but it cannot perform drilling at hard-to-reach locations such as ground level or above head
Solution Approach 1:
The drilling device is segmented into a main drilling unit and a separate deflector attachment. The deflector attachment can be detached and reattached at different positions or orientations, allowing the drilling device to access hard-to-reach locations without modifying the main drilling unit's structure.
Solution Approach 2:
A deflector attachment serves as an intermediary component between the drilling device and the workpiece. This deflector redirects the drill axis at a predetermined angle, enabling the drill to reach locations that would otherwise be inaccessible while keeping the drilling device itself simple and unchanged.
2Adaptability or versatility
If the drilling device is repositioned to access hard-to-reach locations, then accessibility is improved, but positioning becomes challenging and time-consuming
Solution Approach 1:
The deflector attachment is pre-configured with a predetermined angle and fastening means that enable quick attachment and detachment. This preliminary preparation allows the operator to rapidly reposition the drilling device without complex adjustments or time-consuming setup procedures.
Solution Approach 2:
The deflector attachment incorporates fastening means that allow for dynamic and quick adjustment of the drilling device's orientation. The attachment can be rapidly secured or released, enabling the operator to adapt to different working positions efficiently without permanent modifications.
3Adaptability or versatility
If drilling is performed at angles deviating from 90° to reach hard-to-reach locations, then accessibility is improved, but measurement evaluation becomes more complex
Solution Approach 1:
The deflector attachment provides a localized angle adjustment at the point of contact with the workpiece, while the main drilling device and measurement system remain unchanged. This means the measurement evaluation can use the same software and methods as conventional drilling, as the deflector only affects the local drilling angle without altering the measurement data structure.
